it whom it may con-cam.

it known that I, ALICE A. ROBERTS, a n of the United States, and resident of '=orough of Brooklyn, in the county of and State of New York, have incertain new and useful Improves in BottleClosures, of which the fol- .ig is a specification.

this closure I have included means for an 1, even the most rigid conditions.

.lthas been found desirable to close a *ptacle; particularly a milk bottle, in a manner that was not only quick and therefore economical, but also in a way that is air tight and clean: I have provided for all of this and have in addition, means for covering and inclosing the lip or flange of the bottle, therebyprotecting. it from the dirt and germs which are collected thereon during much handling and. transportation.

it have found eiiicient means for accomilis atly to the expense of manufacturing nor eating to any-great extent, to the cost of applying a closure.

The material which I have adopted is strong and somewhat pliable and readily adapts itself to the shaping which I find necessary.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part this specification, in which:

Fi ure 1 is a side elevation of the upper portion of a milk bottle to which n'y closure has been applied. Fig.2 is a yertical section corresponding to Fig. 1. Fig. 3 indlcates the closure disassembled showing more completely each of the separate members.

Similar letters of reference indicate like parts in all the figures where they appear.

This disk is similar and performs all of the functions of the ordinary .disk of this general type, except that the upper side is slightly corrugated near its periphery to receive and retain a supply of waxy material such as paraffin. Two holes 0, 0 are produced in the center of the disk A separating piece D serves an important function so I will describe its peculiarities In plan it is circular, but a side elevation or section reveals that at four places the material has been pressed upward out of a plane "to some little extent.

indicates the cap, thej exterior portion or my closure. It is of one piece and, before being pressed into the shape of a cap, four radial slits are pro uced Whiclinehfly divide the sheet, as it is then, inflfour Twoholes, a, a are produced in the center to match the corresponding holes a, c in the at E.

'.When the parts are constructed according to the foregoing description they are sethrough the ring E so that its endsextend an equal distance oneon each side below the ring. The ends of the wire are then passed through the holes provided for it inthe center of the cap B, and in like manner the separating piece D and the disk C are successively placed upon the extending ends of the wire F, after which the ends of the' wire are bent sharply at right, angles to hold all of the parts firmly together. A wafer G is then secured to the underside of the disk C, by pasting or otherwise in such a manner as to completely cover the ends of' the wire F. My closure is now nearly ready for service, the last though important step is to deposit a supply of araflin on the disk C. I accomplish this y any of the well known means such as submerging the entire cap, or flowing warm paraflin into the cap while it isin an inverted position, or by submerging the disk G into a vessel of just suiiicient diameter -to allow the disk to enter while excluding the remaining'parts.

Modifications may be made. within the scope of the appended claims without'departing from the principle-or sacrificing the advantages of this invention.

The overlapping portion of the ca B caused by the slits may be used wit out I pasting if desired.

- The slits in the capmay be dispensed with by using-a pulpy material which lends itself more readily to the treatment and shaping, such material is known to the arts in the manufacture of electric switches, for the purpose of installation.

The separating piece D may be omitted and a number of thin disks usedto accomplish the desired result.

The parafiin used on the lower disk may be omitted, if such is not desired' The quality of materialand the expenseof manufacture may be varied within a wide range.

Havingflescribed my invention what I claim and desire to secure by Letters Patent is:

1. In a bottle closure, a deep and slitted inclosing cap, a disk having corrugations upon'its upper side secured within sald ca a separating piece arrangedbetween said cap and said disk, a, securing wire extending through said cap, said disk and said separating piece and means for removing or replacing the whole as specified.

2. In a bottle closure, a deep and slitted inclosing cap, a disk having corrugations upon its upper side secured within saidca a separating piece arranged between sald cap and said disk, a securing wire extending through said cap, said disk and said separating piece, and an operating ring heldby said securing wire all combined for joint operation. Signed at New York city in the county of'New York and State of New York this 25th day of January A. D. 1909.
